Android :: OnClick Listener One Function For All Clicks
Nov 14, 2010
In my layout xml file I have set the android:onClick attribute for a Button element to a function in my activity. So when I click the button the function is called with a View as its argument. Are there any information in that View argument that has the id of the button being clicked? I'm trying to figure out if I have to have one onClick function for every element or if I can use one function and switch depending on the id of the element being clicked.

I am working on my first android app and so my first with the Maps API and am experiencing an odd problem. How ever when I click the screen it seems the onClick event is not being run?Have I missed something or am I better off sub classing the MyLocationOverlay I am using and override DispatchTap?How ever i would rather be able to just click anywhere on the map to dispatch the event.

Is there a way to have 1 onClick Lister for many buttons where I can toss a case statement to do things based on what buttons were clicked.
I know I can make 100 different listeners for 100 buttons but I have to think I can create some nifty variables to do it in less lines of code.

I'm creating my first widget and ran into a snag. I have several buttons on this widget and need a way to register an onClick action for each of the buttons. So far I've only found examples where they start a configuration activity from a widget button. Does someone have example code on using buttons in home screen widgets?

The layout xml is as below. I have a RelativeLayout, which contains a TextView. The OnClick listener is set on RelativeLayout. The RelativeLayout has a selector background. What I want is, when user clicks on the RelativeLayout, the background of the RelativeLayout should change, and the color of the text of the TextView should change too. Even though I set color selector for the TextView, only the selector on RelativeLayout works. The color selector on TextView doesn't work. How can I implement change of both RelativeLayout background and text color of TextView when user clicks the layout?

I'm in a process of creating a memory game. My problem is that whenever i click for the second time, i can't even see toggled button. To be clear - first click toggles the togglebutton, so i can see the number it holds, the second click on a different togglebutton is suposed to toggle it, show me the number and then proceed to either set a score +1 if numbers are the same, or reverse them back again if they're different.
Below is the code that i use as my onClick function, i've been thinking about putting some kind of sleep or delay function somwhere in the second "if block" - (if(klikniecia ==2)).
CODE:...........
I think, about setting a delay here, so i can see both of the cards, regardles if the're the same or not before reverting them.
CODE:...................................

i'm looking to get called when the user taps on any part of a map view and i'm having no luck so far. none of these produces as much as a peep when the map view is clicked.i did some googling and found the thread.which suggests that overriding mapView.onTouchEvent() works, though calling setOnTouchListener() doesn't. however, onTouchEvent() didn't work for me.

I have to draw list of 30 articles. I tired using list view but there was some problem as I wanted to user alternate colors like first is white and 2nd is blue where as again 3rd is white and 4th is blue and it goes on..
So I decided to have scrollview and table into it. I set the view using setcontentview which shows loading dialog. then in aysnc task's "doInBackground" method i fetch all articles into the object and then in "onPostExecute" I run a for loop on the object and in each loop i make table row insert article and then insert row into table. and then dismiss loading dialog box.
As i have tabular view in my app and If i remove loading dialog box. While the UI is rendered if someone clicks on other tab. UI is hanged up, After loading all table rows It goes to other tab.

I have an app widget which runs neatly. However, I am unable to highlight a click on a linked item. I've seen it in the standard app widgets like 'Music' and 'Power Control', for instance. Moreover, I've also been studying the Music app widget's source at album_appwidget.xml. The only thing I could think of is the LinearLayout defined at lines 23-35 which states android:clickable="true".Unfortunately, this does not work for me. So does anyone have a hint on how to highlight a click on an app widget? I've tried the LinearLayout, TextView and Button. None of them displayed a border as a highlight.

I have an EditText that shows time. After user clicks the EditText I want to show a TimePickerDialog, so I set a View.OnClickListener to my EditText. But the OnClickListener is behaving wierdly - I touch the EditText and then software keyboard appears (which I don't want). When I touch again, OnClickListener.onClick() is finally called and the dialog appears.What should I do if I want the dialog to appear immediately?

just a short question for a better understanding: I'm developing an app based on the Android 1.5 Framework (with compatibility down to 1.1). But now I read about the new way of implementing click-handlers in Android 1.6 on the Android Developer Blog and I'd really like to use that in my app because it makes developer's life so much easier :) But can I use this (and the 1.6 Framework) without losing backward compatibility to 1.5 and 1.1? Best regards and sorry if this question is dumb [I just didn't find anything via google]

I know how to set a listener for.. let's say a button or a editext so that when clicked some action happens:
buttonOReditextl.setOnClickListener(new View.OnClickListener() { @Override public void onClick(View view) { Action goes here } });
how can I set a onClick event for when the user taps/ clicks on the screen? or the surface.. I'm not sure? I want a picture to be taken when the camera is on.. but don't know how to make a listener to all the camera view instead of having a button to take a picture.

I've got a LinearLayout with a bunch of buttons on it. This panel is always hidden unless a menu item is chosen. When the LinearLayout is shown, I want to detect if the user clicks anywhere outside of the panel so that I can hide it again. Is there a way to do this, maybe with detecting focus changes? I've tried to add an OnFocusChangeListener to the LinearLayout itself (and called setFocusable(true) on it), but the focus change listener never gets called. Furthermore, I'd have to be able to detect if the LinearLayout or any of its children lose focus.

i may get flamed for this question, but help me do it right. I was downloading images from a website and putting them into a database, and then displaying them in an imageview. well to reduce the size of my database, i changed from an imageview to a webview and now only do a Webview.Loaddata(ImageLink). all of this is contained within a listactivity.my problem seems to be that for whatever reason now i dont seem to be capturing the Listclick event any longer

If I go into the sounds and display and select my ringer its loud enough that I put the overall ringtone volume at one notch before the max. The weirdness starts when someone actually calls me. When I get a phone call the ringer sounds like its about half volume, so after the call I go an check and its still one notch from max. Now even weirder is all the clicks and noises throughout android are even quieter. The only way to make them as loud as they should be again seems to be opening voice to text then everything is the volume it should be. I don't have quiet ringtone when picked up turned on, and all my volumes are adjusted right.

I am trying to create a list view where each item will open up a new view and display a picture and text describing the item when said item is selected. I am working with this tutorial novice-tutorials-f8/opening-windows-i-e-webbrowser-reacting-on-clicks- t22.html?hilit=reacting%20on%20Clicks
so is there a way i can use this code to open up a new view
[code]@Override protected void onListItemClick(ListView l, View v, int position, long id){ super.onListItemClick(l, v, position, id);
// Get the item that was clicked Object o = this.getListAdapter().getItem(position); String keyword = o.toString();
// Create an VIEW intent Intent myIntent = null; // The intent will open our anddev.org-board and search for the keyword clicked. myIntent = new Intent("android.intent.action.VIEW", Uri.parse ("" + keyword + "")); // Start the activity startActivity(myIntent);}

I have a DialogPreference in my Preference Activity and would like to know which button was pressed. I have implemented the OnSharedPreferenceChangeListener which does not seem to get triggered when the DialogPreference is selected. I have also tried OnPreferenceClickListener but this gets triggered as soon as the DialogPreference is clicked from the main screen and not when one of the actual dialog buttons was pressed. I think I need to implement onClick for this dialog but I am not sure where to do this. I have looked at the API Demo code and it shows how to create the dialog but not how to determine which button was pressed.
public class Preferences extends PreferenceActivity implements OnSharedPreferenceChangeListener {
private static final String LOG = "test"; private DialogPreference mfactory;
@Override protected void onCreate(Bundle savedInstanceState) { super.onCreate(savedInstanceState); ....................
